The interior project “Sky oasis” is located in the heart of the city of Sofia, rising on one of the last floors of a newly constructed residential building. In this interior design project, we’ve encountered many technical difficulties, one of which was the reduction of the reinforced concrete load-bearing wall, neotectonic studies regarding the vibrations generated in the earth’s crust, the integration of electrochromic foil in the master bathroom, steam room, as well as many other systems. We had to pay attention to the opinion of the whole family and their living habits, but we managed to find a place for every single detail. The role of the interior designer in projects of such rank is to comply with the vision and needs of each member of the family, to frame the ideas, and combine them in the best way!
